In actual engineering, the main calcium-removing precipitant is carbonate. The calcium-removing precipitant is preferably selected from the components of the original high-salt wastewater to reduce the procurement volume of external chemicals. High-sulfate wastewater and the evaporation mother liquor of high-sulfate become the primary choices, and the calcium sulfate precipitation method emerges as the times require. However, the calcium sulfate precipitate has a fast scaling rate, high viscosity, and strong adhesiveness, which often leads to frequent cleaning or washing of the equipment, and even causes the equipment to stop running due to a large amount of adhesion. Summary of the Utility Model

Therefore, they cannot be understood as a limitation on the utility model.

[0029] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0030] In the description of this embodiment, it should be noted that, unless otherwise specified or limited, the terms "disposed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] refer toFigure 1 , an embodiment of the present application provides a precipitation device 1, including: a pool body 2, a plurality of aeration pipes 3 and a blower 4. Among them, the pool body 2 includes a pool wall 200; a liquid is contained in the pool body 2. Exemplarily, the pool body 2 of the precipitation device 1 includes a reaction pool 201, a coagulation pool 202, a flocculation pool 203 and a sedimentation pool 204 that are connected in sequence. Among them, the reaction pool 201 is a pretreatment step in the sewage treatment process, mainly used for chemical reactions to change the properties of pollutants to make them easier to remove. In the reaction pool 201, chemical agents (such as coagulants, calcium agents, pH regulators, etc.) are usually added to promote the coagulation and flocculation processes of pollutants.

[0033] The main function of the coagulation pool 202 is to aggregate suspended particles in water into larger flocs. In the coagulation pool 202, coagulants (such as aluminum sulfate, polyaluminum chloride, etc.) are added to coagulate fine suspended particles, colloidal particles and some dissolved pollutants in water into larger flocs. These flocs then further grow and consolidate in the flocculation pool 203.

[0034] The function of the flocculation pool 203 is to further promote the growth and consolidation of flocs. In the flocculation pool 203, through slow stirring or the action of water flow, the smaller flocs formed in the coagulation pool 202 are aggregated into larger flocs. This process helps to improve the sedimentation efficiency of flocs in the subsequent sedimentation pool 204, thereby more effectively removing pollutants.

[0035] The main function of the sedimentation pool 204 is to perform solid-liquid separation. The flocs formed in the flocculation pool 203 settle to the bottom due to gravity in the sedimentation pool 204, forming precipitates (such as calcium sulfate precipitate). The upper clear water then flows out of the sedimentation pool 204, completing the purification process.

[0036] It should be noted that the precipitation device 1 of the present application can be used to precipitate various substances, and the present application only takes the precipitation of calcium sulfate as an example for illustration.

[0037] Reference Figure 1 , the above-mentioned plurality of aeration pipes 3 are installed on the pool wall 200 of the pool body 2 (reaction pool 201, coagulation pool 202, flocculation pool 203 and sedimentation pool 204); each aeration pipe 3 includes an air outlet 300, and the air outlet 300 is located below the liquid level of the liquid in the pool body 2, and the air outlet 300 is for gas to flow out to disturb the liquid in the pool body 2. Exemplarily, the air outlet 300 is located below the liquid level, and the gas flowing out of the air outlet 300 stirs the liquid in the pool body 2 to keep the liquid in a moving state.

[0038] The above-mentioned reaction tank 201, coagulation tank 202, and flocculation tank 203 are all rectangular in shape, and their four corners are dead zones, that is, a large amount of calcium sulfate precipitate is likely to adhere to the tank body 2 here. Therefore, an air diffuser pipe 3 is respectively provided at each corner of the reaction tank 201, coagulation tank 202, and flocculation tank 203 to interfere with the adhesion of calcium sulfate to the precipitation device 1 through multi-angle aeration, and avoid a large amount of calcium sulfate precipitate from adhering to the tank body 2.

[0039] In this embodiment, due to the existence of other components and structures at the four corners of the sedimentation tank 204, it is inconvenient to install the air diffuser pipe 3. Therefore, an air diffuser pipe 3 is respectively provided on the four side walls of the tank body 2 (that is, the area between two adjacent corners), which can also make the air diffuser pipe 3 ventilate and stir the liquid in the sedimentation tank 204, and avoid a large amount of calcium sulfate precipitate from adhering to the sedimentation tank 204.

[0040] In addition, an air diffuser pipe 3 is also provided in the diversion area 205 between the flocculation tank 203 and the sedimentation tank 204 to ventilate and stir the liquid flowing through the diversion area 205 through the air diffuser pipe 3, and avoid a large amount of calcium sulfate precipitate flowing through here from adhering to the diversion area 205.

[0041] Those skilled in the art can understand that although in this embodiment, an air diffuser pipe 3 is respectively provided at each corner of the reaction tank 201, coagulation tank 202, and flocculation tank 203, and an air diffuser pipe 3 is respectively provided on the four side walls of the sedimentation tank 204. However, in other embodiments, multiple air diffuser pipes 3 can also be provided on the side walls of the reaction tank 201, coagulation tank 202, flocculation tank 203, and sedimentation tank 204, and multiple air diffuser pipes 3 can also be provided at the four corners of the reaction tank 201, coagulation tank 202, and flocculation tank 203. Within the range allowed by the actual situation, one or more air diffuser pipes 3 can also be installed at the four corners of the sedimentation tank 204. In addition, the bottom wall of each of the above-mentioned tank bodies 2 can also be installed with an air diffuser pipe 3 as needed.

[0042] The above-mentioned fan 4 is connected to the air diffuser pipe 3, and the fan 4 is used to provide gas (such as air) for the air diffuser pipe 3. Exemplarily, the fan 4 is a blower. The above-mentioned multiple air diffuser pipes 3 are all communicated with a connecting pipe 5 and are connected to the fan 4 through the connecting pipe 5.

[0043] Adopting the above technical solution, multiple air diffuser pipes 3 are installed on the pool wall 200 of the pool body 2 (reaction tank 201, coagulation tank 202, flocculation tank 203, and sedimentation tank 204). Each air diffuser pipe 3 includes an air outlet 300, and the air outlet 300 is located below the liquid level of the liquid in the pool body 2. Thus, the fan 4 provides gas for the air diffuser pipe 3, so that the gas flows out from the air outlet 300, and the flowing gas stirs the liquid in the pool body 2, interferes with the adhesion of calcium sulfate to the pool body 2, reduces the adhesion speed of calcium sulfate on the pool body 2, reduces the cleaning and washing time of the precipitation device 1, and improves the operation efficiency of the entire precipitation device 1.

[0044] Reference Figure 1 Figure 1 , the precipitation device 1 further includes a connecting pipe 206; the coagulation tank 202 and the flocculation tank 203 are connected through the connecting pipe 206; the air outlet 300 of one of the plurality of aeration pipes 3 is located in the connecting pipe 206. Exemplarily, a part of the connecting pipe 206 is fixed on the bottom wall of the tank body 2, and it can supply the water inside the coagulation tank 202 and the formed flocs into the flocculation tank 203. That is, the inlet of the connecting pipe 206 is located in the coagulation tank 202. One aeration pipe 3 in the coagulation tank 202 includes an extension part 320 and a bending part 321. The extension part 320 extends downward along the depth direction Z of the tank body 2, and the bending part 321 located below it and the extension part 320 are arranged at an obtuse angle. The end of the bending part 321 is provided with an air outlet 300, and the air outlet 300 obliquely extends into the connecting pipe 206 from the inlet of the connecting pipe 206, so that the air outlet 300 discharges air to interfere with the calcium sulfate precipitate flowing through the connecting pipe 206, so as to avoid its adhesion to the inner wall of the connecting pipe 206, causing fouling of the connecting pipe 206 and affecting the connection between the coagulation tank 202 and the flocculation tank 203.

[0045] Exemplarily, the extension part 320 and the bending part 321 of the aeration pipe 3 are arranged at an obtuse angle, that is, the aeration pipe 3 is not directly opposite to the inlet of the connecting pipe 206 to avoid affecting the water flow or the shaking of the position of the aeration pipe 3 caused by the water flow impact. In this embodiment, the included angle formed by the extension part 320 and the bending part 321 of the aeration pipe 3 is 135°, but those skilled in the art can understand that in other embodiments, the specific degree of the included angle formed by the extension part 320 and the bending part 321 of the aeration pipe 3 can be adjusted accordingly, for example, it can also be 130°, 140°, etc.

[0046] Reference Figure 1 Figure 1 , in some possible implementation manners, the precipitation device 1 further includes a plurality of control valves 7. The plurality of control valves 7 are in one-to-one correspondence with and connected to the plurality of aeration pipes 3, and each control valve 7 is used to adjust the gas flow rate of the air outlet 300 of the corresponding aeration pipe 3. That is, the staff can control the gas flow rate flowing out of the aeration pipe 3 through the control valve 7 according to the actual use situation. Further, the supply of gas to the air outlet 300 can also be blocked and opened through the control valve 7.

[0047] In this embodiment, the control valves 7 connected to the aeration pipes 3 in the reaction tank 201, the coagulation tank 202, and the flocculation tank 203 are always open, that is, they are not closed under normal circumstances to assist in forcing the calcium sulfate precipitate in the above three tank bodies 2 to be forcibly disturbed to avoid the calcium sulfate precipitate from adsorbing on the tank body 2.

[0048] In some possible embodiments, the precipitation device 1 further includes a control system (not shown in the figure). The above control valve 7 includes a solenoid valve 700. The control system is connected to the solenoid valve 700 to control the opening and closing time of the solenoid valve 700. Exemplarily, the solenoid valve 700 is connected to the air supply pipe 3 in the sedimentation tank 204, and the control system is connected to the solenoid valve 700, so as to control the opening and closing time of the solenoid valve 700 through the control system, that is, to realize the timed air supply and stop air supply to the air supply pipe 3 through the control system and the solenoid valve 700, thereby controlling the air supply time of the air supply pipe 3 in the sedimentation tank 204, so as to avoid continuous air supply during the precipitation process of calcium sulfate precipitate in the sedimentation tank 204, which affects the normal precipitation of calcium sulfate.

[0049] Those skilled in the art can understand that in other embodiments, the solenoid valve 700 can also be connected to the air supply pipe 3 in the reaction tank 201, the coagulation tank 202, and the flocculation tank 203, and the control system is correspondingly set to realize the control of the air supply time of the air supply pipe 3 in the above three tank bodies 2.

[0050] As Figure 1 and Figure 2 shown, wherein, Figure 2 Fig. shows a perspective view of the air supply pipe 3 installed on the side wall of the pool wall of the pool body 2. Stirrers 6 are provided in both the reaction tank 201 and the coagulation tank 202. The stirrer 6 includes a stirring shaft 600; the air supply pipe 3 includes an L-shaped pipe 301. The L-shaped pipe 301 includes a first pipe portion 302 and a second pipe portion 303 connected to each other. The first pipe portion 302 is fixed on the pool wall 200 of the pool body 2; the second pipe portion 303 is arranged perpendicular to the stirring shaft 600, and an air outlet 300 is provided at one end of the second pipe portion 303 away from the first pipe portion 302; the air outlet 300 is arranged facing the stirring shaft 600. Exemplarily, the first pipe portion 302 extends downward along the height direction Z, and the second pipe portion 303 at its lower end extends along the horizontal direction X and extends to near the stirring shaft 600, so that the air outlet 300 at the end of the second pipe portion 303 faces the stirring shaft 600, so that the gas in the air supply pipe 3 flows out toward the stirring shaft 600, thereby preventing calcium sulfate precipitate from adhering to the stirring shaft 600 and affecting the normal operation of the stirrer 6.

[0051] Referring to Figure 3 , in this embodiment, the air outlet 300 includes a pipe orifice air outlet 310. One end of the air supply pipe 3 extending into the pool body 2 (such as the sedimentation tank 204) is open to form a pipe orifice air outlet 310.

[0052] In addition to the nozzle air outlet 310 provided at the end of the aeration pipe 3, a plurality of openings are provided on the pipe wall of the aeration pipe 3 at intervals along its axial direction, and the plurality of openings form a plurality of pipe wall air outlets 311; along the depth direction of the pool body 2 (i.e., the height direction Z), the cross-sectional area of the pipe wall air outlet 311 closer to the bottom wall of the pool body 2 among the plurality of pipe wall air outlets 311 is larger, so as to ensure the flow rate and velocity of different pipe wall air outlets 311 of the aeration pipe 3 as much as possible. In this embodiment, the aeration pipe 3 extends along the depth direction Z of the pool body 2. Since the nozzle air outlet 310 and the pipe wall air outlet 311 are provided on one aeration pipe 3 at the same time, the nozzle air outlet 310 is naturally located at the lowest position, that is, the position closest to the bottom wall of the pool body 2. Therefore, the cross-sectional area of the nozzle air outlet 310 is the largest, and the cross-sectional area of the pipe wall air outlet 311 above it and adjacent to it is the second largest, and so on upward, gradually decreasing.

[0053] That is, the gas in the aeration pipe 3 at different heights in the pool body 2 is discharged, so as to improve the disturbance effect on the liquid in the pool body 2 and prevent the calcium sulfate precipitate from adhering to the pool body 2.

[0054] Those skilled in the art can understand that in other embodiments, only the nozzle air outlet 310 may be provided, and the pipe wall air outlet 311 may not be provided. That is, the gas in the aeration pipe 3 is directly discharged only from the nozzle air outlet 310, so as to ensure the flow rate and velocity of the gas.

[0055] Such as Figure 3 and Figure 4 As shown, in some possible implementation manners, the precipitation device 1 further includes a fixing component 8. The fixing component 8 includes a buried plate 800, a bracket 801 and a connecting piece 802; wherein, the buried plate 800 is fixed on the pool wall 200. Exemplarily, the buried plate 800 and the pool wall 200 are formed by concrete pouring.

[0056] The above-mentioned bracket 801 is fixedly connected to the buried plate 800. Exemplarily, the bracket 801 is in a rectangular shape with one side open. The bracket 801 is welded to the buried plate 800.

[0057] The above-mentioned connecting piece 802 is connected to the aeration pipe 3, and the connecting piece 802 and the bracket 801 are detachably connected. Exemplarily, the connecting piece 802 is a U-shaped clamp 80. The U-shaped clamp 80 includes a first part 803, a second part 804 and a third part 805 connected in sequence. Among them, the second part 804 is in an arc shape and is sleeved on the aeration pipe 3. The first part 803 and the third part 805 are both provided with external threads. The ends of the first part 803 and the third part 805 both pass through the bracket 801, and nuts 806 are installed at the ends of the first part 803 and the third part 805 to achieve limiting through the nuts 806 and prevent the U-shaped clamp 80 from detaching from the bracket 801, so as to fix the aeration pipe 3 on the pool wall 200 through the U-shaped clamp 80.

[0058] Those skilled in the art can understand that in other embodiments, other connecting members 802 can also be selected to achieve the connection between the aeration pipe 3 and the bracket 801, such as metal strips, etc. Further, other fixing components 8 can also be selected to fix the aeration pipe 3 to the pool wall 200, such as expansion bolts, etc.

[0059] So far, the specific structure of the precipitation device 1 has been clearly described in this application. The embodiments of this application aim to reduce the adhesion speed of calcium sulfate precipitation on the pool body 2. However, those skilled in the art can understand that it is also applicable to other precipitates with the above problems (such as calcium carbonate precipitation), that is, it can also reduce the adhesion speed of the precipitate on the pool body 2, reduce the equipment cleaning or washing time, and improve the operation efficiency of the entire equipment.

[0060] Although the present invention has been illustrated and described by referring to certain preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
